Abstract

Each pixel includes: a light emitting element; a capacitor; a driving transistor that has a control terminal, an input terminal, and an output terminal and supplies a driving current to the light emitting element to emit light; a first switching unit that diode-connects the driving transistor and supplies a data voltage to the driving transistor in response to a scanning signal; and a second switching unit that supplies a driving voltage to the driving transistor and connects the light emitting element and the capacitor to the driving transistor in response to an emission signal, wherein the capacitor is connected to the driving transistor through the first switching unit, stores a control voltage being a function of the data voltage and the threshold voltage of the driving transistor, and is connected to the driving transistor through the second switching unit to supply the control voltage to the driving transistor.
